How to access additional frontends

At the Observability Service Dashboard, we provide several additional frontend URLs under the API tab. As we protect these URLs against unauthorized access, you will receive a 403 Forbidden status code when trying to open the user interface without authentication.

To access an additional frontend (such as Thanos UI, Prometheus UI and Alertmanager UI), you must use your technical user credentials. When you navigate to the respective frontend URL, a standard browser login prompt will appear where you can enter these credentials directly.

Prerequisites

Before you begin, ensure you have the following:

• An active Observability instance.
• Active technical user credentials.

Access the frontends

Once you have your credentials ready, follow these steps to log in to the web interfaces:

1. Log in to the STACKIT Portal.
2. Navigate to your Observability instance.
3. Open the API tab.
4. Click the URL of the frontend you want to access.
5. Enter your technical Username and Password into the browser’s native login prompt.

Troubleshooting

If you experience issues logging in via the browser prompt, review the following common solutions:

• Clear your browser cache: Sometimes old sessions or cached unauthorized responses prevent the login prompt from appearing.
• Check for typos: Ensure you enter the exact username and password generated by the Portal.
• Verify credential status: Ensure your credentials are active and have not been deleted.
